IMPROVEMENT IN CURTAIN-CORD HOLDERS.-

Specification forming part of Letters Patent No. 196,567, dated October30, 1877; application filed February 19, 1877.

To all whom it may concern:

Be it known that I, ALFRED S. DICKINSON, of the city, county, and Stateof New York, have invented certain new and useful Improvements inShade-Fixtures, which improvements are fully set forth in the followingspecification, reference beinghad to the accompanying drawlngs.

The object of this invention is to suspend the shade-roller on both endswith equalstrained shade-cords, so that the roller is maintained inproper horizontal position, and that it is not liable to becomesuspended out of horizontal position by uneven stretch of thesuspension-cords on account of one of them being longer than the other.

In the annexed drawings, Figure l represents a front view of adrop-shade suspended according to my invention. Fig. 2 is a centralvertical section of the same. Fig. 3 represents a detached horizontalsection of the central roller cord catch or stops used with myimprovements. Fig. 4 represents a side view of a modification of thesame; Fig. 5, a front view of the same; Fig. 6, a top view of the same,the block or roller-case shown bisected in the direction shown by theline a b in Fig. 4.

A represents the shade-roller; B, the shade. G 0 represent thesuspension-cords, which pass through the central roller-stops D D, andfrom there over the guides or guide-rollers E E secured inthe topcorners of the Window, and from them said cords pass downeach to thefixture F of each end of the roller, with which they are properlysecured. At a proper distance from the central stops D said cords arefirmly secured together, and hem their junction one of the cordsproceeds single, and its end is attached to the loose end or bar of theshade.

The roller A is provided with the spring for winding, and with thestop-pawl, and the stops G for the shade-bar, as usual. And one of saidstops G is attached to each end of the roller, and is provided properlyfor securing the suspension-cord of each end of the roller. The stops Dare arranged each equidistant (over the guide-rollers) from the ends ofthe spring or shade-roller A, so that the cord by which the one end ofthe roller is suspended is of the same length as the cord by which theother end of the roller is suspended. By this means the roller is notliable to settle with, one end lower than the other or out of horizontalposition, and causing, in consequence, the uneven winding up of theshade. The portions of the suspension-cords from the shade-roller endsto their parts clamped in the catches being of equal length, allow equalstretch and contraction of said cords.

The top portion of a block or frame, P, extends rearward under the topof the window frame, and terminates with vertical legs I I, which have(as also the said part extending rearward) proper holes for wood-screws,with which said frame is firmly secured to the window-frames, as shownin Figs. 4, 5, and 6.

The block or frame P is provided with a central projection, J', and withtwo sockets, oneon each side of said projection, which receive the stopsor catches D. These stops are made with a smooth round or rollersurface, H, and with a spirally-grooved surface, 0. The block or frame Pis so arranged that the stops are carried in an inclined position, theirrear ends being lower than their forward ends. When the cords are slackthey, by gravity, slide from the smooth surface H to the spirallygroovedsurface 0, and are wedged between the grooved surface and the stops J,and thereby the motion of the roller is arrested.

To each roller is provided, on the frame opposite the guide-rollers E, aguard, K, projecting down over the periphery of the roller a shortdistance down from the top, in proper lateral position with the catchingportion of the roller, to prevent the cord catching in passing from theguide-rollers toward the stoprollers. The forward part of each rollerhas a circular flange, L, to guide the cord proper over the roller.

It will be observed that the block, where the pulley-stops D D arepivoted, is brought from the rear of the frame a little forward of theright-angular line from the guide-rollers E, so that when the shade androllerA are being raised to the top of the window, the cords G O, bythrowing the hand down, will readily clamp, and not chafe on the said.roller and to clamp by slacking the cordsin combinashade. tion with thecurtain, roller, 001' s, and guide- What I Elaim as my invention ispulleys, substantially as and for the purpose j The centrally-arrangedcord-stops, having set forth. roller-surfaoeHand spirally-groovedsurface 0, ALFRED S.
